SES-X-FA2 AUDIO OVER SINGLE FIBER EXTENDER
Set Up Instructions
1. Secure the units in a safe location, where they will not be subject to impact and where there is room around the
unit so nothing will interfere with the fiber optic cabling causing it to bend sharply in a tight radius in any way that
can severely affect the signal transfer.
2. Use proper cable management and handling for routing fiber optic cable.
3. Carefully connect your source(s) to the transmitter input(s) and the receiver unit output(s) to your receiving device
input(s) using the XLR connectors on the transmitter and on the receiver unit.
4. Note that audio on the transmitter (Tx) can be Line or Mic level input and the receiver (Rx) is Line level only.
5. CLEAN* the ST fiber optical cable contacts that will be used for connecting the Tx and Rx units and attach the fiber
cable to the ST connections and secure, as you would secure a bayonet BNC. While pressing lightly in on the
connector, twist it in a clockwise direction about 1/8 to 1/4 of a turn and then release. The connector should stay
inserted and have backwards spring pressure holding the bayonet in place.
6. Connect the included power supplies to the transmitter and receiver units, and plug them both into an AC power
source (100-240VAC 50/60Hz) or insert the 9V batteries in both units for remote use.
* CLEAN: All fiber optical cable contacts require cleaning each time before inserting into a device’s outputs or
inputs. Failure to clean the contacts can damage the unit’s optics over time and also render the cable and the
device permanently useless.
Use cleaning kits designed specifically for fiber optics.

1. To prevent fire or shock hazard, do not expose this equipment to high humidity and/or dust. Do
not use in an unprotected outdoor installation nor any area classified as overly damp or wet.
2. The temperature for installation should be kept between 32°F to 140°F (0°C to 60°C).
Avoid direct sunlight exposure or extreme changes of temperature over a short period of time.
3. Do not disassemble the unit as this voids the warranty.
4. Do not drop the unit and avoid heavy impact.
5. This unit should not be permanently installed unless proper ventilation is provided. Any enclosure
openings must not be blocked or covered as they protect the unit from overheating.
6. Before cleaning, turn off the power and unplug the unit from all connections. Use a damp cloth.
Do not use liquid or aerosol cleaners.
7. Do not overload outlets and extension cords as this may result in a risk of fire or electric shock.
8. Enclosure entry is dangerous. Never push objects of any kind, including liquids, into this unit
through openings as they may touch dangerous voltage points or short-out parts that could re-
sult in a fire or electric shock.
9. Do not attempt to open or service this unit yourself as opening or removing covers may expose
you to dangerous voltage and other hazards.
10.There are no user-serviceable parts inside the unit. If the unit requires service contact your au-
thorized dealer, or an authorized repair service company.
